WILLIAM Y. HAS-LET, OF PITTSBURG, PENNSYLVANIA.

To all 'whom 'it may concern? Be it known that I, lVILLrAw H. HAsLn'r,

a citizeny of the United States, residing at Pittsburg. in the county of Allegheny and State. of Pennsylvania. have invented certain new and useful Improvements in Concrete Raiiway-Ties, of which the following is a specification. Y

yMy invention consists of an improvement in railway ties of the class known as concrete reinforced. y

The object of the invention is to provide a concrete tie having ample 'body portion, sti'euing and reinforcing members so incorporated with it as to counteract the usual service strains and also to prevent breakage or injury to the tie in handling, slil'pping,etc.

A further object is to provide a tie hav-` ing means for securing the rail in position .whereby to avoid the use of securing bolts,

screws, nuts or the like, and whereby the rail supporting and securing member is made in one piece and capable of being renewed or replaced if necessary.

, Other objects of the invention are to provide a cheap. serviceable tie which is practically indestructible. having the several foregoing features and together with others as shall be more full)Y hereinafter(lescrihed. Referring to the drawings z--Figure l is a view of a complete tie in side elevation, partly broken away. Fig. 9. is a plan view of the tie.. Fig. 3 is an end view, enlarged. Fig. fl is a similar cross sectional view on theline IV. IV. of Fig. l. Fig. 5 is a perspective detail view showingthe rail-supn porting chair and its manner of mounting inthe 'tie to engage itwith the rail flanges. Fig. 6 is a detail view of one of the bottom shoes. Figf'lis a similar view of the nut locking bearing plate. Fig. 8 is a similar view showing' aV modified fornr of bearing plate. Fig. 9 is a perspective detail view of a shoe having attached fish plate extensions. The interior stiiening frame of the tie consists o't' a .longitudinally arranged rectangular truss having the upper and lower chord members 2, 3, respectively. of plate metal, preferably steel, of' suitable thickness and widthl to give amplestiti'ening eil"- fect to the surrounding concrete, witlrsuf- CONCRETE RAILWAY-TIE.

tieient body to provide against the tcnsional, torsional and comprcssional strains to which the tie is subjected. VSaid upper and lower 4 members 2, 3, are connected by vertical end members l, 4, extending from one of said members 2 or 3 and connected with the other member by bolting or riveting or 'in any 60 other suitable manner, as indicated' at 5. Any other construction or arrangement of the internal truss member Amayfbe adopted to secure the same results and I do not desire: to be limited to the particular eonstruction as shown.

At positions in the tie corresponding to the positions of the rails when in place, are located the shoes 6. Said shoes are of rolled metal having downwardly bent flanges 7, 7, along each side. parallel with the longitudinal center of the tie and at each end upwardly bent flanges or tongues S. 8. somewhat narrower than the width of shoes 6, and extending suiiciently high to bebentlS over upon the rail flanges. to secure them` downwardly in position. Said shoes 6 are set immediately upon the upper chord member Q, the flanges 7 embracing its edges as shown. making snug engagement therewith and {ixedly locating each of said members with relation to each other. t

Laid upon the top of shoe 6 lengthwise of it and engaging the tongues 8 by end recesses 9 Vand corner extensions 10. 10v.is av 85 middle bearing plate. 11, adapted to receive the rail.

At various points along the bottom of the tie I provide retaining bearing shoes 12 of plate metal bent upwardly at each end as at 13. embracing the sides of the tie as shown. said shoes being of any suitable number and location. Two of said shoes are located immediateljv below the rail bearing plates as shown. *R5

For the purpose of securing all of the metal members of the tile fixedly together,

I employ bolts 14 extending transversely from top to bottom. The bolt is provided with an annular abutment or extension 15. 15, at suitable points Vto -bear downwardly and upwardly against the ripper' side of Y lower chord member 3, and under side of upper chord member 2. respectivelythe bolt. extending downwardly through said memi ber and also through the lower shoe 12 and extonding upwardly through'vaid'slxoe and .having a terminal nul, 4in said" cavity, substantially as set forth.

l 7. A rail bearing shoe having Ameans for i 5 securing it to a tie, and upwardly extending .flange engaging ears provided with sh plate extensions, substantially as set forth.

In testimony whereof I hereunto affix my C. M. CLARKE,
